Influence of injected interstitials on α′ precipitation in Fe–Cr alloys under self-ion irradiation

Autor: O. Tissot, C. Pareige, E. Meslin, B. Décamps, J. Henry

Publikováno v: Materials Research Letters, Vol 5, Iss 2, Pp 117-123 (2017)

Depending on the particle used to irradiate Fe–Cr alloys, at the same dose and temperature, α′ precipitation may occur or not. This paper aims at explaining the origin of the absence of α′ precipitation under ion irradiation. A Fe–15at.%Cr
